DETAILED DESCRIPTION

FIG. 1 illustrates a system 100 for identifying clusters of devices 20 . . . 20 n and determining that the devices 20 a . . . 20 n are within a same vehicle 22, in accordance with embodiments of the present invention. Devices 20 a . . . 20 n may comprise global positioning satellite (GPS) devices, mobile computing devices, smart phones, etc. System 100 identifies a cluster of devices (e.g., devices 20 a . . . 20 n) and calculates a position, speed, and direction of each device. The calculations are used to determine that each device is associated with one or more end users (e.g., occupants 18 a . . . 18 n) that are traveling together within a vehicle (e.g., vehicle 22). Additionally, the calculations may be used to determine which of the end users is a driver of the vehicle (e.g., occupant 18 a).

System 100 of FIG. 1 includes a computing system 25 and a GPS system 29 communicatively connected to a vehicle 22. The vehicle 22 includes a computer 14, occupants 18 a . . . 18 n, and associated devices 20 a . . . 20 n (e.g., driver distraction devices). Computer 14 is communicably connected to devices 20 a . . . 20 n, computing system 25 and/or GPS system 29. Computer 14 may include any type of computing system(s) including, inter alia, an automobile integrated computer, a computer (PC), a laptop computer, a tablet, etc. Memory system 8 stores program instructions 17 for communicating with computing system 25 and or GPS system 29 (in communications with a GPS), identifying devices 20 . . . 20 n, determining the devices 20 a . . . 20 n are within a same vehicle 22, and identifying a driver of the vehicle 22. Alternatively, devices 20 a . . . 20 n may directly communicate with computing system 25 and or GPS system 29 for identifying devices 20 . . . 20 n, determining the devices 20 a . . . 20 n are within a same vehicle 22, and identifying a driver of the vehicle 22.

System 100 identifies GPS enabled communications devices in a small area (e.g., occupants of a vehicle), associates the GPS enabled communications devices by device characteristics and GPS coordinated, speed and direction of movement, and identifies a device that is associated with a driver of the vehicle. The aforementioned process is initiated when a local communications receiver (e.g., computing system 25 and/or GPS system 29) aggregates GPS coordinates (of the devices) to locate clusters of co-located devices (i.e., in a confined area). The clusters are compared for relative speed and direction to further identify devices that are determined to be travelling together (e.g., in a same vehicle). Each verified cluster is examined for a relative position and direction in the cluster. A driver position as well as alternative positions are considered and roles for each device in the cluster are determined.

FIG. 2 illustrates an algorithm detailing a process flow enabled by system 2 of FIG. 1 for identifying devices and determining the associated users are located within a same vehicle, in accordance with embodiments of the present invention. Each of the steps in the algorithm of FIG. 2 may be enabled and executed in any order by a computer processor executing computer code. In step 200, GPS data (identifying locations of GPS enabled devices associated with specified users) and/or coordinates is received (e.g., by a computing system 25 and/or GPS system 29 of FIG. 1) from the GPS enabled devices. The GPS data is analyzed. In step 202, a group of users are determined based on results of the analyses on step 200. Each user of the group of users are determined to be located within a specified proximity to each other. In step 204, it is determined (based on results of step 202, and an altitude, velocity, and a vector of the group of users) that the group of users is located within a single vehicle. In step 208, a position of each user (with respect to the vehicle) is determined. In step 212, roles for each user with respect to the vehicle are determined based on each position. The roles may include, inter alia, a driver, a passenger, an instructor, etc. In optional step 214, a size of the vehicle is determined based on a number of users in the group of users and each position of each user. In optional step 218, a type (e.g., a vehicle model, vehicle type such as compact, SUV, etc.) of the vehicle is determined based on a number of users in the group of users, each position of each user, and the size of the vehicle. In step 220, selected functions of each GPS enabled device are controlled based on an associated role of an associated user. For example, a role of a first user may indicate a driver (of the vehicle) role and controlling the functions may include modifying user control functions of the associated GPS enabled device or disabling the associated GPS enabled device.

FIG. 3 illustrates an algorithm detailing a process flow enabled by system 100 of FIG. 1 for updating GPS data within an inference cache for analyses, in accordance with embodiments of the present invention. An inference cache may be comprised by computing system 25 and/or computer 14 of FIG. 1. In step 300, GPS data is received by the inference cache. In step 302, it is determined if a new mobile identification number (MIN) has been received by the computer. A MIN or a mobile subscription identification number (MSIN) comprises a unique 10-digit number used by a wireless carrier to identify a specific mobile phone. A MIN comprises a number that identifies a mobile phone working under TIA standards for cellular and PCS technologies. (e.g., EIA/TIA-553 analog, IS-136 TDMA, IS-95, IS-2000 CDMA, etc.). A MIN comprises a number derived from a 10-digit directory telephone number assigned to a mobile station. Rules for deriving the MIN from the 10-digit telephone number are defined in the IS-95 standard. MIN1 comprises a first or least significant 24 binary digits of the MIN. MIN2 comprises a second part of the MIN containing the 10 most significant binary digits. MIN1, an ESN, and additional other digital input are used during an authentication process. The MIN is used to identify a mobile station. If in step 302, it is determined that a new mobile identification number (MIN) has been received by the computer then in step 305, the MIN is inserted into the inference cache and in step 308, a refresh of the GPS data is obtained. If in step 302, it is determined that a new mobile identification number (MIN) has not been received by the computer then in step 304, the inference cache is updated and in step 308, a refresh of the GPS data is obtained.

FIG. 4 illustrates an algorithm detailing a process flow enabled by system 100 of FIG. 1 for parsing GPS data within an inference cache for analyses, in accordance with embodiments of the present invention. In step 402, a newly retrieved MIN (e.g., as described with respect to steps 302 and 305 in FIG. 3) and associated GPS data is compared to a previous history of GPS data. In step 404, any determined changes between the newly retrieved MIN and the previous history of GPS data are parsed. In step 408, inferences from the changes are determined. For example, similar devices may be clustered by averages of speed and direction. Additionally, a size of an associated vehicle may be inferred based on a direction, location, and number of devices. In step 410, the changes are reevaluated and step 402 is repeated.

FIG. 5 illustrates a GUI 500 identifying a graphical map 502 illustrating clusters 508 a . . . 508 g of users (in vehicles) and associated devices on specified routes of travel, in accordance with embodiments of the present invention. Additionally, GUI 500 presents a compass for displaying a direction of travel. Cluster 508 a comprises a cluster of two users (or occupants) in a vehicle (e.g., a car). Cluster 508 b comprises a cluster of 3 users (or occupants) in a vehicle (e.g., a car). Cluster 508 c comprises a cluster of one user (or occupants) on a bicycle. Cluster 508 d comprises a cluster of multiple users (or occupants) in a bus. Cluster 508 e comprises a cluster of multiple users (or occupants) in a commuter rail. Each of clusters 508 f and 508 g comprises a cluster of one user (or occupant) in a vehicle (e.g., a car). Roles for each user of the clusters 508 a . . . 508 g may be determined via the algorithms of FIGS. 2-4 and as described, supra.

FIG. 6, including FIGS. 6A-6C, illustrates a chart 600 comprising GPS data within an inference cache, in accordance with embodiments of the present invention. The GPS data identifies MINS for devices and associated clusters 508 a . . . 508 g of FIG. 5. Chart 600 additionally identifies locations (e.g., latitude and longitude), vectors, speeds, and inferences related to each of clusters 508 a . . . 508 g.
